Sizely alternatives for Shopify: size charts and recommenders compared
Short answer: Sizely (size.ly) adds a size chart to Shopify with one line of code rather than an app, with size recommenders from $39 a month; app-based alternatives include Kiwi Size Chart for charts, Virtusize and WAIR for recommendations, and Fittly or Rendered Fits for sizing with try-on.
Sizely is a size chart maker used by marketplace sellers and stores. On Shopify its chart is pasted into a Custom Liquid block rather than installed from the App Store, and its Size Quiz (clothing) and Size Match (shoes) recommenders go live on paid plans.
Disclosure: Rendered Fits publishes this page and is one of the alternatives. The facts below come from public Shopify App Store listings and vendor websites checked on 9 November 2026; we have not tested image or recommendation quality side by side. Listings change, so check them before you decide.

When Rendered Fits is the better choice
Rendered Fits is the better choice if you want a Shopify app that recommends a size for each product from your own chart, offers Complete the Look on paid plans (suggesting pieces from the brand's catalogue to wear together), and shows shoppers a try-on preview, with a free plan to start on.

How to choose
- Decide which question your shoppers most need answered: "how will it look on me?", "which size?", or "what goes with it?".
- Shortlist two or three apps whose listings cover that question, and install their free plans or trials on the same products.
- Run the full journey on a phone, from product page to cart, and judge size advice separately from how realistic any image looks.
- Compare conversion and returns over the same period, not vendors' headline claims.
